The final electron-accepting molecule in the electron transport chain is oxygen.
Role of oxygen in the electron transport chain
Oxygen mainly acts as an electron acceptor in the electron transport chain. More specifically, it acts as the final electron acceptor to ensure that oxidative phosphorylation takes place.
Without this final electron acceptor, the electron transport chain will not be able to complete the cycle, and energy molecules in the form of ATP will not be formed.
